ICE-PICK.v

SPECIFICATION forming part of Letters Patent No. 530,866, dated December 11, 1894. Application filed March 9, 1894. Serial No. 503,054. (No model.)A

To @ZZ whom t may concern..-

Be it known that I, HAERIET A.VANH0UTEN, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Ice-Pick, of which the following is a specification.

The invention relates to improvements in ice picks.

The object of the present invention is to improve the construction of ice picks, and to provide a simple and inexpensive percussive device, by which ice may be readily cracked or broken as desired.

The invention consists in the construction and novel combination and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.V

In the vdrawings--Iigure lis a perspective view of anice pick, constructed in accordance with this invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional View.

Like numerals of reference indicate corresponding parts in all the 4figures of the drawings.

l designates an approximately rectangular or oblong casing having a longitudinal bore or opening, receiving a round shank 3, which carries, or is provided, at its lower end with a flathead 4, havinga series of teeth 5 adapted to penetrate and direct the cleavage of ice. The upper end of the shank is retained in the opening or bore of the casing, detachably, by a screw 6, which is arranged in a slot 7 communicating with the bore or opening 2 out of contact with the upper end thereof. By removing the screw 6, the shank may be detached and separated from the casing l when desired.

'lhe upper end of the casing is provided with a solid integral neck 8 at the base of which the casing contacts with the upper end of the shank for driving the teeth into the ice; and the upper end of the neck is threaded and has detachably secured to it a half-round handle 9, which iits the palm of the hand, and which is of sucient weight to give the y desired percussive power, and to prevent the hand of the operator feeling the effects of the blow. The half-round handle is provided with the threaded socket l0 to receive the threaded upper end of the neck.

It will be seen that the head may be placed upon a cake of ice to direct the cleavage in any desired direction, and that by raising the casing and forcing it downward upon the upper end of the shank, any desired number of blows may be given at the same point, whereby great waste and chipping of the ice are prevented. It will also be apparent that the parts of the ice pick may be readily detached and quickly assembled.

Changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle, or sacrificing any of the advantages of this invention.

In an ice pick, the combinationof a shank provided at its lower end with a flat head having teeth, a rectangular casing provided with a longitudinal opening snugly receiving and conforming to the coniiguration of the shank and forming a guide for the same, said casing being provided, intermediate of its ends, with a longitudinal slot and having the solid integral upwardly-projecting neck or shank exteriorly-threaded and forming a solid striking portion for contacting with the upper end of the shank, a screw passing through the slot and engaging the shank and detachably securing the same in the casing, said screw being located a sufficient distance from the upper end of the shank to avoid coming in contactrwithl the upper portion of the casing, and a handle having a threaded socket receiving the upper end of the neck or shank of the casing, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
